CEMENT-TILE-MAKINC- lIIACHT'NE.

Application filed October 1 cement tile making machines and it consistsin the combinations, constructions and arrangements herein described andclaimed.

The object of my invention is to provide a simple and inexpensive deviceby means of which sub-irrigation tile may be made in the ditch in whichit is to be laid.

A further object of my invention is to provide an improved device formaking tile which insures the production of a unifornr grade of wellpacked concrete tile.

A further object of my invention is to provide a device which will cut alongitudinal slot on the underside of the tile.

Other objects and advantages will appear in the following specificationand the novel features of the device will be particularly pointed out inthe appended claims.

My invention is illustrated in the accompanying drawings forming a partof this application and in which Figure 1 is a perspective view of thedevice, Fig. 2 is a longitudinal section through a portion of thedevice, Fig. 3 is a transverse section along the line 3-3 of Fig. 2, andFig. A is a transverse section on the line 4;-4: of Fig. 2.

In carrying out my invention, I provide a casing l of approximately ahemispherical shape, the sides of the casing being straightened,however, in the manner shown in Fig. 3. This casing bears a hopper 2 ofthe shape shown in Fig. 1, the hopper being of greater length thanwidth, this greater length being longitudinal of the casing 1.

Secured to the hopper is a lateral arm 3 which is bent downwardly at Aand is secured at its lower end to a pipe 5 which forms a core. Thispipe is supported at its rear end by a wheel 6 and a second wheel 7 isjournaled on a vertical axis. The purpose of the wheel 7 will beexplained later. A handle 8 is secured by means of a pin 9 to the arm 3and is also secured at 10 to the At 11 I have shown a plunger which isprovided with an opening arranged to re Specification of Letters Patent.

ceive the core 5. This plunger is adapted to enter one end of thecasing 1. The under side of the plunger is 'cut away as shown at 11 toreceive the two cross brackets 12 whose outer ends are secured by rivetsto the casing 1, while their inner ends are secured by screws to thecore 5. These brackets serve to limit the movement of the plunger sincethe latter is provided with a head 11 arranged to engage the brackets 12when the plunger has been retracted sufficiently. The core is connectedby means of a link 13 with a lever 14: pivotally mounted on the pin 9and provided with a handle 15 at its upper end. The core .5 is providedat one end with a cutter 16 of the shape shown in Figs. 1 and 2. p

From the foregoing description of the various parts of the device, theoperation thereof may be readily understood.

As stated above, the machine is designed to make sub-irrigation tile inthe place where it is to be used. Inasmuch as the concrete of which itis made is non-porous, it is desirable to have a means for permittingescape of water and this forms one of the main features of my invention.

In operating the device, the machine is set up as shown in Fig. 1 and bymeans of the handle 15, the plunger 11 is retracted into the positionshown in Fig. 2. Concrete material is now placed in the hopper 2 andpasses downwardly, filling in the space around the core 5. The casing 1forms part of the mold, while the bottom of the ditch forms the otherside of the mold. The handle 15 is now manipulated so as to force theplunger forwardly thereby moving the concrete material out of the openend of the casing. As it is forced past the cutter 16, the latter cuts aslit in the bottom of the pipe, longitudinally of the pipe. As thesection of the completed tile is forced out of the end of the casing,the latter is propelled forwardly, the machine moving on the wheel 6.The wheel 7 is for the purpose of guiding the movement of the machine byits contact with the side walls of the ditch or trench in which the tileis to be laid as it is made. The operation of making the dilferentsections is repeated by working the handle 15 backward and forward asthe new charges of concrete are placed in the hopper.

The device is very simple in construction and very easily operated. Itmakes the tile by compressing, to a certain extent, the materials in theact of forcing the material out of the casing. It permits themanufacture of the tile and the laying of it practically atthe sametime. By the use of this machine, all the sections of pipe are out Witha slot at the bottom so as to permit the escape of Water When the tileis used as sub-irrigation tile.

Manifestly in the operation of the machine it is not necessary to putinto the hopper a certain amount of concrete each time the plunger isretracted, since if desired the hopper may be filled full, or justpartly filled, and this may be done at any time regardless of theposition of the plunger.

I claim:

1. In a cement tile making machine, a casing forming a portion of themold, a hopper carried by said casing, a core, a plunger having anopening through Which the core extends arranged to extend through saidcasing and a cutter carried by one end of said core.

2. In a cement tile making machine, a casing forming a port-ion of themold, aihopper carried by said casing, a plunger having an opening andarranged to extend through said casing, a core extending through saidopening and a rigid cutter carried by one end of said core, the end ofthe cutter extending beyond the Walls of the casing.

3. In a cement tile making machine, a casing forming a portion of themold, a hopper carried by said casing, a core, a plunger having anopening or bore arranged to receive the core, said plunger beingarranged to ex tend into said casing, and a rigid cutter carried by saidcore and disposed centrally of the casing, the edge of the cutter towardthe plunger being curved, and the end of the cutter extending beyond theWalls of the casing for forming a central slot in the Walls of the tile.
